Cymbidium Orchids will eventually need dividing and repotting. We show you how to divide them and re pot them to make more plants, better flowers and promote new strong growth.
The traditional time to divide Cyms is in spring after flowering, some growers prefer late summer. As long as its not to cold, the time is not that crucial.
It is best to divide the larger clumps into smaller clumps of 3 - 4 bulbs. The older bulbs (back bulbs) can be removed or left.
Smaller divisions of 1 - 2 bulbs may not flower the first year after division.
Trim of any dead or damaged roots.
Potting mixes vary greatly, as long as you use a good proportion of orchid bark mix and the drainage is good you will have few problems.
You can repot in a specialist cymbidium orchid mix or make your own try a 50 % pine bark and 50 % coir peat mix. The potting mix that is best will depend on your climate and watering regime. Use a pot that will provide a restricted root run, cymbidiums grow better with a confined root system.
Do not fertilise for about 2 months after dividing.
I inherited my fathers orchids in 2015 he loved his orchids & was very proud of them he’d have them out in the front garden for everyone to see. I have divided a few times, have given some away to friends as I have an abundance & every time they flower it reminds me of dad. I wasn’t really sure if I was doing the dividing correctly & your video really shows how easy it is to do, so thank you I can now feel confident & will keep enjoying them & remembering my dad, thanks JohnnyA 🌱
Thank you for this!! My dad loved orchids and had a beautiful garden of them. He passed away a few months ago and I want to keep them going in his memory. I had no idea what I was doing. Now I'm ready to keep his orchids looking beautiful 🥹
honestly, I love your accent...you should record audiobooks! Not kidding
I have this orchids. I repotted 2 of them. I seperated the bulbs and put in the pots. now I learned the correct way of repotting them. I follow your method to repot the rest of theem. Thank you so much. It was great presentation.
Best video on cymbidiums I have watched thus far. Thank you. Now need to divide mine.
Definitely best
😀 thank you for all that wonderful information 👍👍
Thanks Mary.
I think I will repot my Cymbidium next year. I just got it this year , it had 2 spikes on it and beautiful flowers. It is spring. Paula from Mexico.
Hello Paula, if it flowered well this year just give it a little fertiliser and repot after flowering next year. It is headed into winter in Australia, however still nice weather....
johnny A Thank you.
Thank you very informative. I enjoyed your direction on repotting
Cymbidium Orchids.
Thank you so very much for this very well presented and indeed most informative clip. I am about to repot mine, I have heaps of them and was a little nervous and unsure to how I was going to go about this. You have given me the confidence and knowledge to do this. Once again, I thank you.
So Rebel . . How did they turn out?
Gd instructor. Patient..tqvm.
Thank you for great information.... I am feeling a lot more confident to try this myself
Thanks Louise, Cymbidiums are fairly tough, so you should be OK with them.
All of orchid I love cymbidium most so thank you for repotting
Thankyou so much for this. I don't feel so bad using an axe to split the ball today....pheeew.
Thanks for the very informative video. I had a big pot lost under my Lemon tree, it was very neglected & failed to flower this year. I just repotted it, I divided & got rid of lots of dead matter & actually put them all back in the same pot with new Orchid mix. I thought they liked to be crowded hence why I did this. Hope they are as tough as you say as I I found this video after I had already repotted it!
Hello Di, In new potting mix and cleaned up they should flower. You can always divide them in a year or two if needed. A little specialist orchid fertiliser will also be beneficial.
thank you that was very helpful, I learnt a lot and will now repot my orchids.
Very Usefull. I have many orchids and they need a repotting , thank you
Ah Australia. . .heaven on earth. Such a beautiful garden, and the birds. Thank you Johhny, I just loved your video and have subscribed. I have a passion for cyms. The Golden orchid displayed at the start is the very one I find most beautiful. The pink one also, just so. These along with browns are the colours I am going for. Splendid golden, luscious chocolate and glorious pinks. I just divided 3 orchids neglected for a few years and was concerned that I had trimmed too much root. I also hosed thoroughly all the old mix out and repotted in a bought mix and sprayed with Yates orchid fertiliser. But I'm relieved now that I see yours are similar after trimming. I'm not sure whether I should leave them outside or put them in the bathroom. . . sheltered Melbourne garden. 14° nights for now. Just in from Adelaide a large brown Khan Flame Tuscany Champion, 170mm pot, 4 flower spikes. Thanks for info not to disturb spikes by dividing now. I'm nervous in case with the move from SA it needs to come in. It's in a sheltered but not too shaded spot, need shade cloth. Also many new single growth cyms, 68ml pots . . I dont know whether to repot a bit or leave them be.
If you want flowers this year, leave them, also the move and acclimatisation might be best to leave for now.
Thos vidio was very helpful. Where i live its difficult to obtain cymbidium orchids and the one i have is more than ready to be divided. I will do so now with confidence. Thank you😃
Thanks for the comment Dean, good luck with your orchids.
very informative and easy to understand , great video , thanks john
Very good video with helpful tips.
Thanks Kim, glad it was useful for you.... any questions, just ask.
An awesome monster. Would love that!
very good demostration thanks
Thank you for doing this; super useful and clearly explained! Now to do mine :)
Very clear and helpful -- thanks!
Thank you so much! I bought two of these half price around Easter just last month. I have a big yellow and a smaller red, both with multiple bulbs and finished bloom now. I'm following your advice here :)
Thank you so much for this.
Thank you 😊
Ótimo seu replanto suas plantas são lindas 👏❤❤😘
Excellent video ! Thanks
Very informative
Thanks Sue.
Excellent video, I'm more confident in repotting it now.
wow! so beautiful, I like it
Thanks for the vdo sir easy way
I just watched your video which was very informative however I think I may have cut the roots a little as they were very long. Is that a problem?
Hello Beth, I would think that as long as you left some roots on them they will be fine, Cymbidiums are very tough....
Many thanks. Also one further question, the orchids I have ate my fathers very old orchids which were overgrown through years of neglect . Some leaves have black spots which I have read is fungus. What do I do and do you have a video on this.? Thank you. Beth
@@bethsarlos7960 Hello Beth, You can use a fungicide, that would be available a most nurseries or garden centres. A DIY option is a very weak bleach solution, this can also work. We have used 1 Gallon of water (3.5 to 4 litres) with 1 fluid oz (30ml) of bleach in a spray bottle. You do need to make sure its a weak solution....... I would also repot them and get them into a position with good air circulation.
Thanks again Johnny. I've started to reply them and will go out and buy some fungicide. Most helpful.
Excellent! So you mean that putting it into clumps of two or three will improve the next year blomming? I was thought it was just the oppossite! (keeping the whole mass was better). Greeting from Argentina.
Raul . . I'm not sure that's what he meant. Because some say it's most optimal to leave the large clump together. In other words, he may not have been showing how to reduce to 3 because 3 promotes better than the large clump . . . Simply that because people want to divide this is how it's done. When he said "3 encourages more flowers later" he was referring to 3 compared to 1. Not comparing to the original clump. I don't know what he'd say about that. I hope he reads this and answers
PS . Greetings from OZ!
Good simple and easy to repot and explained well, thank you
ThAT's wonderful Sir, Can you send me those bulbs you don't want to plant, I would be very greatful... thanks
we can change which months
Danke. Temperatur???
I live in north Florida where we have hot, sunny summers and for a few months in winter lows average 40s (last night was a cold 29). I planted a lovely, adult cymbidium in the ground about 5 years ago, and it has never flowered. I would like to dig it up and try it in a pot. Do you have any thoughts on what time of the year I should do that.
They can be a little shy to flower in the ground, best with a restricted root run, so potting is a good idea. Generally in spring after flowering is the best time, however if they are not showing any signs of flowering by mid spring, I would do it then. Also try a little specialist orchid, low nitrogen high potash type fertiliser, a week or two after repotting. Hope this works, good luck and let us know how it goes.
How old a "youngest" backbulb can be? How long will it take for a thick green Pseudobulb to turn into a backbulb? My cymbidium has 4 small dry backbulbs, 2 huge green pseudobulbs, 2 smaller size and one very slim PB. Three of the green PB have sent 2 shoots each from their bottoms. I wonder how long it will take for those shoots to turn into a regular size pseudobulb? If you could, please, make a video about life stages of cybm pseudobulbs. There aren't videos about it in youtube. Thank you in advance!🌹
No real rule for this, usually 3-4 years however it varies greatly. I will see if we can set up a pot of cyms to show the cycle.
@@johnnyAGardening thank you!
After you divide your orchids can you use Neutrog Strike Back Orchids.
After dividing we usually put a pinch of 12 month Osmocote in the pot above a layer of potting mix, and then plant the cym. this means the roots go looking for the fertiliser and then back strike every month or so. If you are just using back strike, wait 1 month after dividing and repotting
What is potting mix?
It has been suggested to me that when I repot I should plant them offcentre in the pot is this necessary ?
The theory is that you plant with the bulb near the back of the pot with the new bulb facing the front so the bulb has room to grow into. It is not essential however can be of some benefit.
You know you can keep on the back bulbs or you can plant individually and they may shoot out new groths
Thanks Stef, something we did not mention. Yes, any left over back bulbs can be potted up and they can send out new roots and growth (not always) Usually around 2 - 4 years to flowering from back bulbs.
I heard that the back bulbs can still be viable. How would you plant those? Oops, you answered that!
As singles, 2 to a 1 gallon pot?
I just bought some really huge plants at an estate sale, i'm ready to give them a new home and look forward to their gorgeous flowers next season.
Thank you!
Hello Jill, occasionally they can be, so if you want to, you could try 2 to a pot. Give it a go and see what happens .....
Hello sir i like cymbidium ,may i buy from you,how may i buy from you i am from philipines
i am not sure on your views.. of them being contained .. i thought they were an Epiphytic orchid that does not have contained roots could you explain further on this
also clay V plastic pots which is better would the roots stick to the pots and does the clay wick away moisture from the roots..
One problem is over potting, so we like to use pots that hold the root system, however are not so large that the excess potting medium can remain overly moist.
And although they are epiphytic, they adapt well to pots. They are not surrounded by growing media when they are grown as epiphytes.
We have grown cymbidiums in both plastic and terracotta pots and have not had issues with moisture loss. It will depend on where you keep the pots. We have not had issues with the roots sticking to terracotta pots.
We also have some growing in the ground where they have been very happy for a number of years.
Some smaller ones are in hanging baskets, also doing well.
Hi John , thank you for getting back to me and explaining,, i have 4 cym and lots of other phlas. omcids.brassia/ miltass etc..
do you have any videos on dividing those types of orchids please.. . i think i need to do this and am not sure on how to go about it.. many thanks.
Mate was that sterilised?
The pots were washed and scrubbed with hot water. The secateurs wiped over with methylated spirits. Should have mentioned that.
Isn't it better to re-pot into a slightly bigger pot rather than splitting the plant?
You can do that, however eventually the clumps become too big and congested and this will inhibit growth and flowering. This also allows you to divide them into smaller plants so you have more pots of them, to give away, or sell if so desired..
I saw some workers at the Santa Barbara Orchid Estate (USA) and they were quite ruthless when dividing the rootball. They used a hatchet and chopped away !!
I guess Cym. doesn't mind a root trimming.
Hello Randy, yes they a tough plant. All of the divisions from that clump are happy and growing well. A few flower spikes appearing, so don't be afraid to have a go at it. We are also growing some miniature Cyms, hope to have a video on that soon.
john allman .... yes...my plant is very rootbound. I also had to cut the pot to remove it. I'll split it and remove the dead backbulbs. It's my fav Cym., so I hope it survives. It is a species, so it's hardy.
john allman ... hey, how should i treat the newly divided/potted Cym's ?
do they want a boost of nutrients ? ...or should they dry out a bit ?
I'm assuming that they should be out of sun for a week or two, to re-adjust.
Out of the sun for 3 -4 weeks, however good filtered light. A light feed after 3 - 4 weeks. If its very dry, water them.
Hi, can I repot mid Feb (Adelaide) or wait till after this years flowers? (I don't want to jeopardise flowering) thanks
You can re-pot in Feb, however as they can start flowering in May, you will need to VERY careful not to damage/disturb the new flower spikes, which will be just developing. If you want the flowers, I would wait until after flowering.
@@johnnyAGardening thanks for your reply; I'll wait so I can enjoy the flowers
@@johnnyAGardening a disappointing year - flowers in only one out of thirty pots :(
@@doubledark2 Yes, and for us as well. usually masses of flowers this year a few spikes..... will try to work out why.
When do i divide them mine never flower
Divide them in spring, and not too large a pot.
Thank you
How big should the pot be
@@agnescassar7604 With about 2 inches (5cm) room around the division itself to the edge of the pot. This will give it 2 - 3 years growth room yet still a constricted space which cymbidiums do like.
@@johnnyAGardening thank you
This must be the mild mannered version of repotting because my repotting ...well the air was blue, I’m no lady!
Hello Davina, we know what you mean, expletives deleted for RUclips
Did your back bulbs have roots?
Ours had no roots, HOWEVER If you are very patient, you can replant them and keep them just just a little moist and they may, or may not reshoot , they can take 3-4 years to grow (If they do regrow)
Thank you!
I know it's not the right time of year (what is pls?), but do you think I can repot my two cymbidiums now - May - in Sydney, John? Thanks.
You should repot after flowering, HOWEVER, they are tough plants so IF you have to, you could do it now. If you repot with minimum root disturbance and do not divide them, they should be OK and MAY even still flower this year. If you divide and disturb the roots you do run the danger of setting them back in flowering and growth.
@@johnnyAGardening I've done just that and kept root disturbance to a minimum. I think they'll get better ventilation in the new pots. Thanks so much for your advice. :)
I think you should be OK with that, may still flower this year. Good luck with them.
The roots are talking over the pot.
And that is why we repot the orchids
Not a bad presentation but you forgot to tell that you need to sterilise your instruments. Also it is recognised that Cymbidiums take four years to flower. You need to back bulbs, current growth and new growth is possible.
Thank Grahame, I will try to incorporate that into the description. I guess you grow a few Cymbidiums.
I also kill a few. But Orchids are the toughest plants in the world and Cymbidiums the easiest to grow. I enjoyed the video it is the best I have seen and that includes most garden programs.
Wow, the roots look rotted
The root system was very congested, however not rotted at all. Because of the congestion some were dead, this is why we divide them, to provide a more healthy root system.
